Airtac PB Pen-type Cylinder PB16X15U
The AirTAC Airtac PB Pen-type Cylinder PB16X15U is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 15mm stroke. Its slim round barrel and back cover are stainless steel, the M5×0.8 ports keep plumbing compact, and the fast, low-friction piston suits high-cycle small-part handling.

About the Airtac PB Pen-type Cylinder PB16X15U
The AirTAC PB16X15U is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It generates 100.5 N of push and 90.7 N of pull at 0.5 MPa, utilizing a 5 mm piston rod with an M10x1.0 rod-end thread. The slim SUS304 stainless barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments while keeping end-of-arm tooling light.
This specific configuration features a U-type back cover with a 90-degree perpendicular air inlet for flat plumbing, plus an M5x0.8 port. Deceleration relies on a fixed TPU bumper at each end rather than an adjustable air cushion. Without live air pressure, the piston drifts freely, so applications requiring fail-safe holding need an external rod lock.

Specifications follow the official AirTAC PB pen-size datasheet. Piston rod and barrel are stainless steel. Confirm bore, stroke and back-cover option against the product label before installation.
Theoretical Output Force (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 100.5 N | 90.7 N |
| 0.7 MPa (max) | 140.7 N | 126.9 N |
Values are taken from the AirTAC PB thrust table. Because pull acts on the rod-side annular area, pull force is always lower than push. Actual usable force is reduced by friction — size with a margin.

Where the Airtac PB Pen-type Cylinder PB16X15U Is Used
PCB Depaneling Jig
Actuates a short cutting blade to singulate printed circuit boards, utilizing the 15 mm stroke and 90-degree side inlet to maintain a flat wiring profile within a dense electronics assembly fixture.
Carton Flap Folder
Tucks small corrugated carton flaps at high speed, where the fixed TPU bumper handles the repetitive impact and the 100.5 N push force easily overcomes light cardboard resistance.
Sorting Diverter Arm
Pushes lightweight parcels off a routing belt using a compact 5.1 kg vertical lift capacity, fitting neatly into tight transfer gaps where a standard profile cylinder would be too bulky.
Is the Airtac PB Pen-type Cylinder PB16X15U the Right Cylinder?
When sizing this 16 mm bore actuator, stepping down to a 12 mm bore yields 56.5 N of push at 0.5 MPa, while there is no larger standard bore in the PB family. Plan for a safe working load of roughly 60 N, which is about 60% of the 100.5 N theoretical figure, to account for seal friction. For vertical lifts, this equates to safely raising around 5.1 kg with a 2:1 safety margin.
The thin 5 mm rod provides coaxial thrust but is not designed for side loads, so add a linear bearing if guiding off-axis masses. Because the fixed TPU bumper only absorbs energy in the final few millimeters, metering out the exhaust is recommended when cycling heavy tooling at high speeds. Confirm your ordering essentials: 16 mm bore, 15 mm stroke, M5x0.8 port, U 90-degree side inlet, and no sensor magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Slim pen body vs. a standard round cylinder
- ✓ Back cover: CB / U / R inlet direction
- ✓ Magnet (S) for sensors?
- ✓ Mounting: LB / FA / CJ or front thread
- ✓ Keep the load coaxial — avoid side load
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 0.7 MPa operating pressure.
- check Keep the load coaxial; avoid side load on the thin rod.
- check Do not dismantle the front or back cover.
- check Fit dust caps to ports during long-term storage.
- check Installation by qualified personnel per AirTAC docs.
Airtac PB Pen-type Cylinder PB16X15U FAQ
At 0.5 MPa, the push force is 100.5 N and the pull force is 90.7 N. At the maximum operating pressure of 0.7 MPa, the push is 140.7 N and the pull is 126.9 N. The operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s.
The U back cover provides a 90-degree perpendicular air inlet for flat plumbing. Instead of an adjustable air cushion, it uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters. If cycling heavy masses at high speeds, you should meter-out the exhaust or add an external shock absorber.
